传统小口径武器一般采用弹簧式反后坐装置，其结构简单可靠但后坐力偏大。为进一步降低自动机后坐力，本文采用一种气体液压式反后坐缓冲装置，编制后坐运动数值仿真程序。仿真结果表明，在保证后坐位移的情况下，相比弹簧式缓冲器，采用气液式缓冲装置自动机最大后坐力下降了39%。对后坐运动过程进行流体仿真计算，并与数值计算结果进行对比，两者误差在10%以内，进一步验证了仿真结果。
The recoil systems of spring type are used in a wide range of existing small caliber weapons because of the advantages of simple structure. However, the recoil is larger than other types. To reduce the recoil further, a recoil system of gas-liquid type is studied in this paper. Numerical simulated program of recoil motion is designed. The simulation results indicate that the recoil reduced 39% used gas-liquid mechanism compared with the spring mechanism under the similar recoil displacement. The fluid simulation is conducted. The error values of numerical and fluid simulation are within 10%, which further validates the simulation results.
